THERMAL RADIATION PHENOMENA. VOLUME V. RADIATION HYDRODYNAMICS OF HIGH TEMPERATURE AIR

Abstract

This report introduces the reader to radiation hydrodynamics (RH) and discusses its application to fireballs in the atmosphere. After formulating the basic equations of RH, special attention is given to the radiative transfer problem. Several methods for solving the equations of transfer are touched upon but special emphasis is placed on the two stream method with a frequency averaging procedure, which is specifically designed for use with finite zone sizes. A version of the FIREBALL code which utilizes this approach is described. The physics of fireballs is illustrated with the example of a one kiloton detonation at sea level density and without interference from the ground. Some remarks are made on scaling procedures for extending the result to higher yields and altitudes. Estimates are made of the validity of the models. (Author)
